I WANT TO DOUBLE DATE

This is an experience of a confused fellow, maintain integrity or follow his game and double date where no one gets hurt at the end.
if a guy chests, its not bad, infact, it is normal but when a lady does, it becomes abnormal and wrong. is this not inequality?
I have been in this relationship with a guy i loved so much and have given everything i had to him. On his own part he has been caring and due to his commitment, i thought he really did loved me. Despite all warnings from my friend that he is not faithful, i stayed and still trusted him, risked my relationship with my friends for what i share with him.
I am sure by now, you know where i am heading to.
Yes , your guess is right, my friends are right as well, he was cheating, he had been cheating all along. I felt really terrible and felt my whole world had crumbled.

It was a beautiful day and i decided to go with my friends to a park since he claimed he was busy at work that afternoon and would even get home late. I only got to realise my boyfriend gave excuse to stay late at work in order to keep a date with his secret love; how ridiculous.

Trust, i was disappointed, i felt so miserable and my friend were there to tell me " did we not tell u?" though, that was the last thing i wanted to hear then but they were still right. knowing my boyfriend did not see me in the park, i decided to ask him how he spent his day and guess the answer " babe, i was at work all day, it was so busy i could not even get a lunch" what a lie.

my friends said i should tell him i know about him double deal and quit, i really don't to cause i do care about him, i also will play the same game with him since thats what he wants.
